Claims. (C1. sos-469) This invention relates to spinning and twisting 'spindles and more particularly tooiling devices therefor.

It has been found inthe operation of such 5 spindles that a crooked or unbalanced spindle Will sometimes pump oil out of a spindle base and cause a spindle to run dry in a comparatively short time after olli-ng. It has also been found that lint or dirt accumulated around the upper part of the spindle base will sometimes Y115 that pumping or siphoni-ng of oil lfrom the spindle base will be effectively prevented.

More specifically, l2 provide means for airtight sealing of the `oil supply passage,4 so that escape of oilwill be prevented by external atmospheric pressure.

My invention further relates to arrangements and combinations of arts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawing, in which Fig. 1 is a sectional side elevation of a spindle embodying my improvements;

Fig. 2 is a plan view thereof;

Fig. 3 is a View similar to Fig. 2 but showing the parts in a different position;

Fig. 4 is a side elevation of a combined doffer guard and oil cover; and

Fig. 5 is a side elevation, partly in section, of

a valve member with the doffer guard pivoted thereto.

Referring to the drawing, I have shown a portion of a spindle rail I0 having a spindle base II mounted therein and secured by the usual clamping nut I2. A spindle blade I4 is provided with a whirl I5 and is rotatably mounted in a bushing or bolster I6, inserted in a cylindrical bearing I'l in the upper part of the base Il. The lower part of the base is provided with an enlarged oil chamber I8.

The parts thus far described are all of the usual construction.

The device for supplying oil to the chamber I8 comprises a laterally projecting portion 20 having an oil passage 2| therein, and an upright member 22 having a cylindrical passage 23 intersecting the passage 2|, and having also an inclined branch passage 24 intersecting the passage 23. A valve memberv 3U is mounted in the cylin- 55 drical passage 23 and is provided with a central l-l; recess 3'! (Fig. 5) in its lower end portion and Withla -side port 32 communicating therewith. lA combined doifer guard and oil cover 35 is plvotally connected'to the upper end of the valve member .30 by a cross pin 36. One end portion 113:5r 4B of the part A35 normally extends over the edge of the whirl I5 and forms a guard which prevents upward displacement of the spindle during the doiling operation. The 'other end portion' 4I of .the part 35 is inclined outwardly and downwardlyil and forms a cover for the upper end of the inclined passage 24. n The portion 4l excludes dirt but is not depended on for sealing action. Side flanges 42 (Fig. 5) are also provided, which flanges embrace the sides of theupright member 22 of .155 the foiling device when the parts are in the position shown in Figs, l and 2 and prevent' accidental angular displacementthereof. The part 35 may 'desirably be formed of sheet metal. i

A stop 44` is provided on the upper end of the 20 upright member 22, which stop limits angular movement of the part 35 and valve member 30 to In order to prevent upwardl displacement of the valve member 30, an annular groove 46 (Figs. 25 l and 5) is provided in the upper part of the member 30, and a cross pin 48 is inserted through the upright member 22 to hold the valve member from axial displacement.

When the parts are in the position shown in 30 Figs. 1 and 2, the port 32 in the valve member 30 is at 90 from the passage 24 and the oiling device is thus effectively sealed. When the part 35 and valve member 30 are turned to the position shown in Fig. 3, the oil passage 24 is un- 35 covered and the port 32 is aligned with the passage 24, so that oil may be supplied to the spindle base through the passage 24, port 32, recess 3I and passage 2I. Also when the parts are in the position shown in Fig. 3, the doifer guard is 40 inoperative and the spindle may be removed if desired.

Having thus described the details of construction of my improved spindle oiling device, the use and advantages thereof Will be readily apparent. The outstanding feature is the effective sealing of the oil passages by the valve member 30, so that no air can enter the passage 2| or the oil chamber I8. Consequentlir no oil can be pumped or siphoned out of the upper end of the cylindrical bearing I'I, as such removal of oil would produce a partial vacuum in the chamber I8 and the escape of oil would be prevented by the atmospheric pressure at the top of the bearing I1.

2 I thus secure all of the advantages of a certain old type of spindle having no provision for oiling except by removal ,of the spindle and supplying oil directly through the spindle opening,

Wlule at the same time I retain the advantagesV 0f the more modern type of spindle having provision by which the spindles may be oiled while the machine is running and without removal of the spindles. i

In addition, I secure the advantage of sealing the oil supply passage air-tight, so that pumpin or siphoning of oil is made impossible.

Having thus described my invention andthe advantages thereof, I do not wish to be limited` to the details herein disclosed, otherwise than as set forth in the claims, but what Iclaim isz-- l. In a spindle, a spindle base having an oil supply device at one side'withY an oil passage therethrough, a valve member intersectingsaid passage and effective to open and close' said `passage at a point between the ends of said passage and substantially removed from the outer end thereof, and a doffer guard mounted on said valveY member and by which said member may be turned, said guard being also effective to cover the outer end vof said passagewhen said passage is closed by said valve member.

2. In a spindle, a spindle base having an oil supply device at one side with an oil passage therethrough, a valve member intersecting said passage and eiective to open and close said lpassage at a point between the ends of said passage and substantially removed from the outer'end thereof, and a combined doffer guard and oil cover pivotally mounted on said valve member and by which said member maybe turned, the outer end of said passage being'covered bysaid guard when ,the passage is closed by said valve and said guard having a free swinging movement relative to said valve member.

3. In a spindle, a spindle base having an oil supply device at one side With an oil passage therethrough, a rotatable valve member to open and close said passage, a combined doffer guard and oil cover pivotally mounted on said valve member to swing about an axis perpendicular to the axis of said valve member and by which said memberr may be turned, and means to retain said valve member and said combined guard and cover in operative position in said spindle base.

4. In a spindle, a spindle base having an oil supply device at one side with an oil passage therethrough, means to cover said passage at its cuter supply end, means to close said passage at a point between its ends and substantially removed from both ends of said passage against ow of oil or air through said passage, and manual means to actuate said rst means to uncover the outer end of said passage and to simultaneously actuate said second means to open said passage at said intermediate point, said first and second means being mechanically and operatively connected to each other. v t

5. In a spindle, a spindle base having an oil supply device at one Side with an oil passage in the lower part of said device, a second oil passage intersecting said rst oil passage, a cylindrical valve member mounted in said second passage and havinga central recess, an oil inlet passage intersecting said second passage, a port 30 KARL W.
